Squamy cosying up to derasa ?

[cabenin]

My squamy keeps moving over to and resting against my derasa. I have moved the Squamy a couple of times (derasa is fixed to the bottom) but it keeps going back to the same place. Both clams look happy but the way they are set up it seems that this cannot be good for the derasa. one end of the derasa is up against the middle of the squamy shell. Do you think I should try to separate them more aggresviely? Thank you
